Q185. Refer to the exhibit.

An administrator is troubleshooting a time synchronization problem for the router time to another Cisco IOS XE-based device that has recently undergone hardening. Which action resolves the issue?

Allow NTP in the ingress ACL on 10.1.225.40 by permitting UDP destined to port 123.

Ensure that he CPE router has a valid route to 10.1.255. 40 for NTP and rectify if not reachable.

NTP service is disabled and must be enabled on 10.1.225.40.

Allow NTP in the ingress ACL on 10.1.255.40 by permitting TCP destined to port 123.

Q186. Refer to the exhibit.

An OSPF neighbor relationship between R2 and R3 is showing stuck in EXCHANGE/EXSTART state. The neighbor is established between R1 and R2. The network engineer can ping from R2 to R3 and vice versa, but the neighbor is still down. Which action resolves the issue?

Restore the Layer 2/Layer 3 conectivity issue in the ISP network.

Match MTU on both router interfaces or ignore MTU.

Administrative “shut then no shut” both router interfaces.

Enable OSPF on the interface, which is required.

After two OSPF neighboring routers establish bi-directional communication and complete DR/BDR election (on multi-access networks), the routers transition to the exstart state. In this state, the neighboring routers establish a master/slave relationship and determine the initial database descriptor (DBD) sequence number to use while exchanging DBD packets.
Neighbors Stuck in Exstart/Exchange State
The problem occurs most frequently when attempting to run OSPF between a Cisco router and another vendor’s router. The problem occurs when the maximum transmission unit (MTU) settings for neighboring router interfaces don’t match. If the router with the higher MTU sends a packet larger that the MTU set on the neighboring router, the neighboring router ignores the packet.

Q187. Refer the exhibit.

Which action resolves intermittent connectivity observed with the SNMP trap packets?

Decrease the committed burst Size of the mgmt class map

Increase the CIR of the mgmt class map

Add a new class map to match TCP traffic

Add one new entry in the ACL 120 to permit the UDP port 161

Q188. Refer to the exhibit.

Which statement about R1 is true?

OSPF redistributes RIP routes only if they have a tag of one.

RIP learned routes are distributed to OSPF with a tag value of one.

R1 adds one to the metric for RIP learned routes before redistributing to OSPF.

RIP routes are redistributed to OSPF without any changes.

Q189. An engineer configured a Cisco router to send reliable and encrypted notifications for any events to the management server. It was noticed that the notification messages are reliable but not encrypted. Which action resolves the issue?

Configure all devices for SNMPv3 informs with priv.

Configure all devices for SNMPv3 informs with auth.

Configure all devices for SNMPv3 traps with auth.

Configure all devices for SNMPv3 traps with priv.

Explanation
SNMP notifications can be sent as traps or inform requests. Traps are unreliable because the receiver does not send acknowledgments when this device receives traps.”Send reliable and encrypted notifications for any events” so it is SNMP notifications. For encryption we need to configure “priv”.

Q190. Refer to the exhibit.

An administrator that is connected to the console does not see debug messages when remote users log in. Which action ensures that debug messages are displayed for remote logins?

Enter the transport input ssh configuration command.

Enter the terminal monitor exec command.

Enter the logging console debugging configuration command.

Enter the aaa new-model configuration command.

Q191. Two MPLS routers, R1 and R2, are not directly connected and have an established LDP session running between them. What type of LDP session is this?

Remote LDP session

Direct LDP session

Tunneled LDP session

Targeted LDP session

Q192. Refer to the exhibit.

debug ip flow

debug ip sla error

debug ip routing

debug ip packet

debug ip routing This command enables debugging messages related to the routing table.

Q193. Refer to the exhibit.

Users in the branch network of 2001:db8:0:4::/64 report that they cannot access the Internet. Which command is issued in IPv6 router EIGRP 100 configuration mode to solve this issue?

Issue the eigrp stub command on R1

Issue the no neighbor stub command on R2.

Issue the eighr command on R2.

Issue the no eighrp stub command on R2.

Q194. Refer to the exhibit.

Users report that IP addresses cannot be acquired from the DHCP server The DHCP server is configured as shown About 30O total nonconcurrent users are using this DHCP server, but none of them are active for more than two hours per day Which action fixes the issue within the current resources”

Configure the DHCP lease time to a bigger value

Add the network 192.168.2.0 255.255.255.0 command to the DHCP pool

Q197. Which SNMP verification command shows the encryption and authentication protocols that are
used in SNMPV3?

SNMP users. The following example specifies the username as abcd with authentication method
of MD5 and encryption method of 3DES.

Reference: http://www.cisco.com/c/en/us/td/docs/ios/12_4t/12_4t2/snmpv3ae.html
Note: The command “show snmp group” displays the names of groups on the router and the
security model, the status of the different views, and the storage type of each group. Below is an
example of this command.
